Application filed January 20, 1922. Serial No. 530,653.

To all 'whom t may concern.L

Beit known that I, LoUrs P. Fnoowloz, a at Brooklyn, in the county ofKings and t-ate of New York, have invented certain new' and usefulImprovements in a Hydraulic Hoist for Automobiles, of which thefollowing is a specification.

This invention relates to motor vehicles and more particularly .to theturning means therefor.

This invention has for its object the prof vision of means whereby a.motor vehicle may be turned in a short space so as to dispense with thenecessity of running the vehicle forwardly andbackwardly a number oftimes when it is desired to turn around.

*A further object is to provide a turning device for motor vehicleswhich is simple to operate, durable in use, and cheap to manufacture. jOther objects and advantages of the invention will bejapparent duringthe course of the following description.

In the accompanying drawing formin a part of this application and inwhich 1ke numerals are employed to designate like `parts throughout thesame,

Figure l is a side elevation of the inveni tion applied, parts beingbroken away.

Figure 2 is a group perspective of a power transmitting member embodiedin the invention.

Figure 3 is a detail sectional view through the invention.

In the drawing wherein for the purpose of illustration is shown apreferred embodiment ofthe invention, the numeral 6 designates a motor.As illustrated in Figure 1, the motor 6 is provided with a drive shaft 7to which a clutch 8 is connected.

The invention forming the subject matf ter of this Qapplication residesin novel means whereby the forward portion of the vehicle may beelevatcd and moved in an arcuate path and the invention consists of acylinder 8 adapted to receive Huid pressure from a pipe 9 lhavingcontrol means preferably located adjacent the drivers seat of thevehicle so that when desired fluid pressure may be introduced into thecylinder.

When the fluid under pressure is introduced into the cylinder .8 thepiston 12 in the cylinder is moved downwardly :for` in1- partmg acorresponding movement to the upwardly extending branch 14 of ahorizontally disposed axle 15. A turning wheel 18 is provided with lahub 19 which is rotatably mopnted on the axle 15 and having a pinion 20which meshes with the pinion 22 on the lower end of a shaft 23.

The shaft 23 is slidably extended' into a sleeve 26 and is connectedthereto by inc ans of a radially arranged lug 28 which as illustrated inFigure 3, is slidable in a longitudinal slot or groove 30 in the innerwall of the sleeve. By reason of this construction the rotation of thelsleeve 26 will rotate the shaft 23 so that thewheel 18 will also berotated for moving the vehicle in the proper direction.

The upper end of the sleeve 26 is formed with a gear 33 adapted to beengaged by a pinion 34 having a yhub section 36 feathered on the shaftof the engine. When the gear 34 is inmesh with thegar 33 the sleeve 26is of course rotated for imparting a rotary movement to as wheel 18.However, the pinion 34 is rotated only when the improved turning deviceis in operation and the gear by means of a fork 39 having connectionwith a crank arm 40. The cranky arm 40 is connected with an adjustingrod 42 having a handle 43 arranged adjacent'the operators seat. Withreference to Figure 1, it will be seen that -the adjusting rod 42 ismovable through the dash 46 of the vehicle and is provided with lockingmeans for engagement with a holding member 48 mounted on the dash.v

In operation, when it is desired to turn the vehicle, fluid underpressure is introduced into the cylinder for depressing the piston andthereby elevating the forward portion of the vehicle. When the forwardportion of the vehicle has thus been elevated, the gear 34 is moved intomesh with the pinion 33 and the operation of the engine rotates thewheel 18 so that the vehicle 1s .turned to the desired extent. When thevehicle has been turned the gear 34 is released `from engagement withthe pinion 33 and the Afluid under-pressure is allowed to escape fromthe cylinder 8 1 so as to allow` 34 may be moved to its inoperativeposition luc rigidly connected to the cylinder 8 by a connecting bar 50.The upper portion of the sheath is provided with anti-friction elements53'which contact with the under side of the gear 53 whereby to reducefriction between the gear 33 and the sheath to a minimum. The sheath 49forms'a' reliable means for su porting the sleeve 26 and for Thecombination with a vehicle having an en 'ne provided with a drive shaft,of a,

cy inder carried by the vehicle adaptedto receive fluid under pressure,`a horizontal axle having one end extending upwardly and provided with apiston within said cylinder, a ground contact7 Wheel carried by theelother end of said axle, a vertical fshaft carried by said horizontalaxle for turning movement with relation thereto, beveled gearsconnecting said horizontal axle and said vertical shaft, a housing aboutthe. upper end of said vertical shaft, a gear carried by said housingfeathered to said`vertical shaft Yadapted to permit said shaft to slidebringing said second gear in mesh with said gear carried by said housingforJ driving the ground wheel. n In testimony whereof,-I have affixed mysignature in the presence of two Witnesses.
